Reevaluating Amdahl's law
TL;DR: Dans cet article, il est question de l'importance, pour la communaute scientifique informatique, de venir a bout du «blocage mental» contre le parallelisme massif impose par une mauvaise utilisation de la formule de Amdahl.

Reevaluating Amdahl's law
TL;DR: In this article, Amdahl et al. describe a "blocage mental" contre le parallelisme massif impose par une mauvaise utilisation of the formule de Amdahls.
Journal ArticleDOI
Development of Parallel Methods for a $1024$-Processor Hypercube
TL;DR: The scaled-problem paradigm better reveals the capabilities of large ensembles, and permits detection of subtle hardware-induced load imbalances that may become increasingly important as parallel processors increase in node count.
Journal ArticleDOI
Beating Floating Point at its Own Game: Posit Arithmetic
TL;DR: A new data type called a posit is designed as a direct drop-in replacement for IEEE Standard 754 floating-point numbers (floats), and provides compelling advantages over floats, including larger dynamic range, higher accuracy, better closure, bitwise identical results across systems, simpler hardware, and simpler exception handling.

Paper: Toward a better parallel performance metric
Xian-He Sun,John L. Gustafson +1 more
TL;DR: Theoretical and experimental results show that the most commonly used performance metric, parallel speedup, is 'unfair', in that it favors slow processors and poorly coded programs.
